(No model.) Patented in Germany February 28, 1885, No. 32,862; in Spain July 20,1885, No. 7,278; in France April 27, 188.5,No. 168,518; in Belgium August 27, 1885, No. 68,656, and in England May 6,1885,

To all 1077,0712 it may concern.-

Be it known that I, FELIX KiiHNE, residing I at the city of Berlin, in the Kingdom of Prussia, German Empire, have invented a new and useful Improvement in Cloth-Pressing Machines, of which the following is a full and true specification.

This invention relates to improvements in revolving presses for pressing fabrics; and it consists of means whereby the fabrics are pressed between a traveling web and the faces of cylinders.

The construction of the press is shown in the accompanying drawings, in which Figure I is asectional. elevation of my improved press. Fig. II is an end elevation; Figs. III to V, diagrammatic views illustrating modifications.

In the sectional elevation at Fig. I of the accompanying drawings are shown two cylinders, A B, of ordinary construction, around which passes an endless web, m, lined with a suitable materialas paper, metal, or silk impregnated with suitable substances, or other like materials with glazed surface. The web should be of such anature that it does not crease, warp, stretch, or tearin working. The web iskept tightly stretched by the adjustment of the cylinders, so that the pressure exercised by it upon the cylinders is considerable.

The material of which the endless web is constructed will vary according to the nature and dressing of the material to be treated. It may be of leather, sheet metal, caoutchouc, sail-cloth, oil-cloth, &c.

For producing the required tension of the endless web, and corresponding pressure between it and the cylinders, the bearings of the In order to avoid undue strain upon the truuuions of the cylinders, a roller or cylinder, 0, is in some cases interposed between them, running in fixed bearings, upon which roller paper or other fabric is wound,'so as to adjust its diameter to the exact distance between the cylinders A B, so that these are made to take a bearing upon the cylinder 0,, and thus their trunnions are relieved of pressure.

The fabric a to be treated is wound upon beam D, and arranged within the space inclosed by the web, the shaft of the beam turning in bearings supported by the frame. The fabric is passed from the beam D between the cylinder 0 and the cylinder A, at the left, and between the web m and the surface of said cylinder A. Thence it is carried over the cylinder B, at the right, between it and the web, and is eventually wound upon beam E.

The cylinders A B may both be heated internally by any suitable known means; but in order to obtain the above-described effect of the ordinary papering-press, one cylinder-for instance, that to which the fabric last passes is kept cold, being artificially cooled, if requisite, by circulation of cold water, and the other cylinder is kept hot. Thus each cylinder has a hollow journal, a, at each end, and with one journal of each, beyond the box H, is coupled, so as to permit the journal to turn one end of a flexible pipe, h, the other end of which is coupled to a supply-pipe, 71/ or h, the pipe 7i supplying hot water, and the pipe 71. supplying cold water, and the opposite j ournal of each cylinder is coupled in like manner to a flexible discharge-pipe, is, so that the water, after passing through the cylinder or cylinders, is conducted away.

By the use of flexible pipes the adjustment of the cylinders to and from each other is permitted.

The fabric a will first be subjected to pressure under the influence of heat by one cylinder, A, and after passing in contact with the air on its way from one cylinder to the other will be effectually cooled by contact with the second cylinder while still subject to the same pressure. Should it be desired to increase the pressure, or to act upon the outer surface of the fabric, rollers d (I, either cold or heated, may be applied against the cylinders A, as shown in Fig. III.

. 5 If desired, a steaming or glazing cylinder,

and carrying the fabric, substantially as described.

2. The combination of the two cylinders, ad- 3' ustable bearings therefor, a surrounding web, 20 and beams within the space inclosed by the web, and a roller arranged between the cylinders and bearing thereon, substantially as described.

In testimony whereof I have signed my name 2 5 to this specification in the presence of two subscribing witnesses.

FELIX KUHNE.
